Abstract (en)
[origin: EP0429330A1] Process and plant for the continuous manufacture of coloured panels by continuously depositing on a belt conveyor a bulk-impregnated substance resulting from the kneading of metered quantities of particles such as vermiculite and of an inorganic binder, by forming it into a base layer, by depositing on this layer another layer consisting of particles bulk-impregnated with a coloured binder, in subjecting the set of layers to a precompression and by then cutting them up into panels which, after passing through a press, are subjected to a heat treatment in an oven. <??>Advantages which are inherent in continuous manufacture, to which is added the advantage of a panel coloured by adding to the base layer a bulk-coloured layer which can itself be two-coloured. <IMAGE>
